Liming plant fully commissioned and magnesium removal from brine commences as brine is pumped from pond 4B to 4A

Gas pipeline completed and awaiting connection by Gas Atacama

Construction projected to be completed on time and within budget

In terms of physical progress the construction program is approximately 80% complete. A total of approximately US$178m has been spent or committed via executed contracts in the construction project to date.

The southern bore field brine duct was commissioned on 26th February and now delivers brine directly into pond 4B from the southern field. This replaces the temporary trench system which was moving brine to the northern field intermediate pump station.

The liming plant commissioning was officially completed on 10th February. This was marginally behind the end of January target due to issues with the electrical control circuits for the ball mill motor. With the liming plant now commissioned, magnesium removal from the brine is occurring as brine is pumped from pond 4B to 4A. This is an important step in the process of brine purification.

The gas pipeline has been completed and we are now awaiting the gas branch line connection from Gas Atacama to be completed in order to commission the use of natural gas. This is expected to occur in the next two months. There are two gas generators on site with a further seven units in transit.

The reverse osmosis plant is ready for delivery and is undergoing the import approval process, the completion of which is imminent.

Construction works continue on the lithium processing plant, finished goods warehouse and the soda ash warehouse.
